Is there a function available for this? I couldn't find anything. Right now I am computing P^t*P by using MatPtAP with A=identity, but I was hoping there is another way where I don't need to set up the identity matrix. Use petsc-dev and MatTransposeMatMult(P,P,...,&PtP) ________________________________ This e-mail message (including any attachments) is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
